Application filed. February 7, 1924.

To all whom it may concern:

Be it known that I, I-IUBERT R. HUM- PHREY, a citizen of the United States, residing at the city and county of Kalamazoo,

State of Michigan, have invented certain new and useful Improvements in Gas Heaters, of which the following is a specification.

This invention relates to improvements in gas heaters.

The main object of this invention is to provide a gas heater of the type shown in the United States Letter Patent No. 1,280, 740, issued October 8, 1918, to Alfred E. Humphrey, an improved means for removably supporting the radiating elements.

Objects pertaining to details and economies of construction and operation of my improvements will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. I,

A structure which is a preferred einbot iment of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. I is a front elevation of a gas heater embodying the features of my invention, only such parts being illustrated as are deemed necessary to disclose a practical embodiment of my present invention.

Fig. II is a detail vertical section on a line corresponding to line 22 of F I showing structural details.

Fig. III is a detail view partially in vertical section on a line corresponding to line 3-3 of Fig. II.

In the drawing the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference indicate similar parts throughout the several views.

Referring to the drawing 1 designates the casing structure generally. As the details of this casing form no part of this invention I do not illustrate or describe such details herein.

Within the casing I mount a base plat 2 and upon this is supported a iirebacl: having a forwardly projecting flange-like overhang 1 at the top. Foraminated tubular radiating elements 5 are ar *anged upon Serial No. 691,179.

the base plate in front of the fireback with their upper ends below but adjacent to the overhang I of the fireback.

The burner is provided with tips 6 which are aligned with the openings 7 in the plate 2 over which the radiants are disposed. The radiants are provided with notches 8 in their upper ends, the notches being aligned and engaged by the rod 9 which has laterally turned ends 10 providing supporting arms which are arranged through the holes 11 in the overhang, thus adjustably supporting the rod so that it may be lifted to release the radiants.

The ends of the arms 10 are threaded to receive the spherical nuts 12 by means of which the rod 9 is retained. This provides an effective support for the radiants which is very inconspicuous and, at the same time, one which does not detract from the appear ance of the heater.

I have illustrated my improvements in one of the adaptations which I have found very satisfactory in commercial use. I believe that the disclosure made will enable others skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent- 1. In a gas heater, the combination with the casing, of a fireback having an overhang at the top, the overhang having vertical holes adjacent the ends thereof, radiants disposed in front of said fireback with their upper ends below but adjacent to said overhang, said radiants having aligned recesses in their upper ends, and a retaining rod having laterally turned ends disposed through openings in said overhang of said fireback whereby it is adjustably supported to engage said recesses in said radiants.

2. In a gas stove, the combination of a casing, a fireback having an overhang at its top, radiants having aligned notches in their upper ends, and a retaining rod engaging said notches and having lateral arm ends adjustably disposed through said fireback.

3. In a gas stove, the combination with a casing, of a fireback having an overhang at the top, radiants disposed in front of said fireback with their upper ends adjacent to said overhang, and a retaining rod having laterally turned ends disposed through openings in said overhang whereby said rod is adjustably supported to engage the upper ends of said radiants.

4:. In a gas stove, the combination with a casing, of a fireback, radiants disposed in front of said firebaok, and a retaining rod engageable with said radiants for reniovably supporting them in position and having lateral arms arranged through said firebaok. 10

In Witness whereof, I have hereunto set my hand.

HUBERT R. HUMPHREY. [L. s.]
